Members of the RAS (see HRAS; MIM 190020) subfamily of GTPases function in signal transduction as GTP/GDP-regulated switches that cycle between inactive GDP- and active GTP-bound states. Guanine nucleotide exchange factors (GEFs), such as RAPGEF2, serve as RAS activators by promoting acquisition of GTP to maintain the active GTP-bound state and are the key link between cell surface receptors and RAS activation (Rebhun et al., 2000 [PubMed 10934204]).[supplied by OMIM, Mar 2008]

Interaction
Interacts with CDH1, CTNNB1 and TJP1 (By similarity). Interacts (via C-terminal domain) with MAGI2 (via PDZ and WW domains); the interaction occurs before or after NGF stimulation. Interacts with KIDINS220 and NTRK1; the interactions occur after NGF stimulation (By similarity). Found in a complex, at least composed of KIDINS220, MAGI2, NTRK1 and RAPGEF2; the complex is mainly formed at late endosomes in a neuronal growth factor (NGF)-dependent manner. Interacts (via C-terminal domain) with NEDD4 (via WW domains); this interaction leads to ubiquitination and degradation via the proteasome pathway in a cAMP-independent manner. Interacts with MAGI1 isoform 3 (via PDZ domain). Interacts with ADRB1 (via C-terminal PDZ motif); the interaction is direct. Interacts (via Ras-associating domain) with RAP1A (via GTP-bound active form). Interacts weakly with HRAS (via GDP- and GTP-bound forms). Interacts (via C-terminal domain) with MAGI2 (via PDZ and WW domains).
